Okay, i'll try to give the weirdest one i heard without getting banned. similar to someone above, my boss when I was working construction one summer up near the canadian border in vermont said this to a group of people, and everyone else seemed to move on without hesitation. It went like this:
Carpenter: How's your tractor runnin' boss?
Foreman: Ahh, F---in' motor's skippin' like a f---in' whor* in a pumpkin' patch!
